EXTENSIN-CHANDELIER.

SPECIFICATION forming part of Letters Patent No. 224,442, dated February 10, 1880.

Application filed October 2s, 1879.

To all 'whom tt mor/y concern Be it known that I, JOSEPH KLNTZ, of West Meriden, in the county of New VHaven and State of Connecticut, have invented a newlinprovement in Extension-Chandeliers, of which the following is a specication. i

My improvements relate to the means for retaining the extension-rod in any position, as drawn out to lengthen the chandelier, and for 1o releasing the same, so that the spring may act to draw up the rod.` I make use of a sliderod having its surface grooved or ribbed concentrically and sliding ina collar that is tted with loose sectional'nuts or clamping-blocks, which are inclosed Within a beveled cup or ring. The cup is moved in one direction by a spring to force the nuts inward and clamp the slide-rod, and isliitted for movement by hand to release the nuts by means of a trigger placedd in a convenient position operating through a sliding tube that is connected to the cup.

The construction and operation will be more particularly described with reference to the accompanying drawings, whereinj i 'Figure 1 is a central vertical section of the chandelier. Fig. 2 is a partial section, showing the clamping devices in enlarged size. Fig. 3 is ahorizontal section online x a; of Fig. l. Fig. 4 is a horizontal section on line y yof Fig. 2. y i

Similar letters of reference indicate corresponding parts.

The slide-rod a is formed at its upper end with the pendent cap b, that is fitted for being suspended, and passes through the cap c of the collare, that is secured on the upper end of the outer tube, d. On the lower end of tube Z is secured the crown-ring e, to which the branching arms of the chandelier will beconnected, but are not shown, and beneaththe ring e is a knob',j', by which the tube d'is'handled.

g g are spiral springs connected with cap b and ring e, and tending to draw'tube d and its attached parts upward on the rod a.

The rod a is formed upon its outer surface with concentric creases or ribs, as shown at l, throughout its length, which are rounded upon their surfaces. Y

The cap c is formed with a depending annular fiange within collar c and around rod a,

which -flange is apertured radially to receive Kthe sectional nut or clamping pins or blocks h h, thatare formed at their inner ends with creases .or grooves corresponding with the ribbed surface of the rod a, with which the blocks h are intended to iit. The outer ends of blocks h are formed with rounded, inclined,

or beveled projections 2, as shown. Within collar c, around the depending flange of the 6o cap c', is a ring or cup, t', the inner surface of which is in contact with the projections 2 of blocks h, and is beveled so that the upwardV movement of cup t' will force blocks h inward. This cup t' is fitted rigidly on the upper end of 65 an inner tube, 7c, which, for convenience of manipulation, extends tothe-lower end of tube d and into a recess of the knob f, at which placethe tube 7c rests upon a spiral spring,

t, that tends to force tube 7c upward, and by 7o thev cup or ring t" force blocks 71. inward to clamp rod a. In the recess of knob f is fitted a lever or trigger, m, which is apertured to pass around tube k above the pins n, that project from le, and the moving end of lever m extends outside through a slot'inr knob f. By this construction the blocks h act automatically to retain the tube dand its attached parts in any position to which it may be drawn down on the rod a.

v To release the blocksV h for drawing down the chandelier or allowing it to be drawn up by springs g, the knob f is to be grasped and tri ggerm depressed, which action draws down the ring or cup t' and frees the blocks h from 85 pressure, so that they will be thrown out by the pressure caused by springs g or the strength applied to draw down the tube d.

It will be seen that the ribs or creases of the rod c serve to increase the friction between 9o the rod and clampingblo'cks, so that less. pressure is required to hold the parts 5 but it is evident that by increasing the pressure the ribs ma)7 be made quite small, or even a smooth tube used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In extension-chandeliers, the combination, with the slide-rod a, and extension-tube d, of roo the cap c', radial clam ping blocks or pins h, and beveled cup or ring i, the ring i being itted to clamp or release the block h, substantially as and for the purposes specified.

2. In extensionfchandeliers, the combination, with the slide-rod a and extension-tube d, of the cap c', radial clamping-blocks h, beveled cup or ring z', tube 7c, spring l, and trigger, substantially as described and shown, and for the purposes set forth.
